  • Solvent-Free Synthesis of c-Axis Oriented ZSM-5 Crystals with Enhanced Methanol to Gasoline Catalytic Activity

    ZSM-5 crystals with controllable c-axis length were successfully synthesized through a one-pot solvent-free route, with urea as an additive. X-ray diffraction patterns (XRD) show that the prepared samples exhibit high crystallinity. N2 adsorption–desorption isotherms and mercury intrusion porosimetry (MIP) analysis together with TEM observations indicate that micro-, meso-, and ...

  • Heavy Metals Water Testing Powered by DNA

    Water pollution is a worldwide problem affecting developing and developed countries alike. Heavy metal contaminants are one prevalent type of water pollutant. They are persistent in the environment once d is charged and removal from source waters is necessary to ensure a clean drinking water supply. The problem of heavy metal pollution arises from several sources. Heavy metals such as uranium can ...

  • Adsorption characteristics of ammonium exchange by zeolite and the optimal application in the tertiary treatment of coking wastewater using response surface methodology

    Natural zeolite is a favorable NH4+-ion exchanger in the tertiary wastewater treatment. In this study, a natural Chinese zeolite was anatomized using the mercury injection method, X-ray diffraction, and scanning electron micrographs. The kinetic process of ammonium adsorption onto the zeolite was best described by the pseudo second order model; the adsorption equilibrium data ...

  • Fabrication and evaluation of an attapulgite membrane as the filter for recycling blowdown water from industrial boilers

    Continuous blowdown water (CBW) from industrial boilers is of great quantity and energy, and therefore worth recycling. According to the data from a long period of monitoring, carbonate and sulfate were documented as the main contaminants in CBW. Herein, an attapulgite (ATP) membrane was prepared on a macroporous Al2O3 support through solid state sintering. The prepared membrane ...

  • Methylmercury, Fish Consumption, and the Precautionary Principle

    This paper considers several broad issues in the context of probabilistic assessment of the benefits of curtailing mercury (Hg) emissions from U.S. coal fired power plants, based on information developed from recent literature and ...

  • Heavy Metals in Vehicles

    Untitled Document Introduction Starting from September 1999, Ökopol has been performing a study on heavy metals in vehicles which was commissioned by DG ...

  • New boiler MACT and affiliated rules proposed

    EPA proposed three related rules (with final rules expected by December 16, 2010), intended to reduce the emission of hazardous air pollutants (HAPs) from industrial, commercial, and institutional boilers and process heaters as well as commercial and industrial solid waste incinerators. Simultaneously, it also proposed a definition of solid waste that could potentially affect some units currently ...

  • Patterns of Hg Bioaccumulation and Transfer in Aquatic Food Webs Across Multi-lake Studies in the Northeast US

    The northeastern USA receives some of the highest levels of atmospheric mercury deposition of any region in North America. Moreover, fish from many lakes in this region carry Hg burdens that present health risks to both human and wildlife consumers. The overarching goal of this study was to identify the attributes of lakes in this region that are most likely associated with high Hg burdens in ...

  • PC MACT proposal may signal widespread change

    On May 6, 2009, EPA proposed amendments to the National Emission Standards for Hazardous Air Pollutants from the Portland Cement Manufacturing Industry (PC MACT) in response to numerous petitions and court mandates. The proposed revisions present significant challenges to the portland cement industry by establishing a new lower maximum achievable control technology (MACT) floor that would require ...

  • On the suitability of Portable X-Ray Fluorescence Analyzers for rapid screening of toxic

    Abstract X-Ray Fluorescence spectrometry (XRF) has been routinely used for alloy testing, determination of Pb in paint, and determination of Cd in plastic. However, its use to screen for toxic elements in food and medicinal products has been surprisingly limited to date. While XRF is less sensitive than atomic spectrometry methods such as ICP-AES and ICP-MS, it offers a number of significant ...
